The Broquet fuel catalyst units comes in two forms - the In-Tank unit and the In-Line unit. The In-Tank unit consists of a metal gauze containing a pre-determined number of pellets, and the complete unit is inserted into the bottom of the fuel tank. The In-Line unit consists of a metal tube with the gauze and pellets fitted inside.  This unit is then fitted into the fuel supply line of a vehicle or boat.


Either method is as effective for all engines and the final choice rests with the customer. However, it is generally found that the In-Tank units are more cost-effective for smaller applications, such as motorcycles and cars, whereas the In-Line units are recommended for the larger engined applications; trucks, buses, larger generators, boats etc...    




A wide range of testing has been carried out in-house and independently on a variety of cars, trucks, boats and boilers.  The testing has included those carried out in the laboratory. However it is the testing carried out under real-world conditions that shows the full package of benefits of Broquet. In truth every customer who uses Broquet for the first time, is carrying out their own test, as their investment in the product must be proven to themselves.  Therefore the large volume of testimonial letters and referrals from our many, many thousands of customers is testament to the high level of satisfaction experienced by these customers We are pleased to provide a summary of formal testing carried out on Broquet on many different applications under many different conditions.

The pellet that is the Broquet fuel treatment catalyst, is a

combination of different metals based upon the origial

formulation developed by Henry Broquet in 1941. It has however been

modified over the years in order to meet the increasing demands on

fuels and oils, by modern day engines, whilst still meeting the

requirements of older engines. The manufacturing process is not a

simple process, as it involves the blending together of the different

metals at precise times and temperatures. For this reason the

manufacturing process is subject to a strict quality assurance

program.  This is of course vitally important to ensure that each

Broquet pellet is to perform safely, reliably and consistently over its

long, active life.




  • Bangladesh :

     A simple on-the-road test (shown right) conducted for a                      customer in Bangladesh provides evidence of how quick

     and effective Broquet can be. 


     Results show that on a 125cc motorcycle an extra 80                        kilometers (or 12%) was achieved in only a 6 week period
